9.
Aggregated teams (802.3ad \ LACP and GEC\FEC) must be connected to
only a single switch that supports IEEE 802.3a, LACP or GEC/FEC.
10.
It is not recommended to connect any team to a hub, as hubs only support
half duplex. Hubs should be connected to a team for troubleshooting
purposes only. Disabling the device driver of a network adapter participating
in an LACP or GEC/FEC team may have adverse affects with network
connectivity. QLogic recommends that the adapter first be physically
disconnected from the switch before disabling the device driver to avoid a
network connection loss.
11.
Verify the base (Miniport) and team (intermediate) drivers are from the same
release package.
12.
Test the connectivity to each physical adapter prior to teaming.
13.
Test the failover and fallback behavior of the team before placing into a
production environment.
14.
When moving from a nonproduction network to a production network, it is
strongly recommended to test again for failover and fallback.
15.
Test the performance behavior of the team before placing into a production
environment.
16.
Network teaming is not supported when running iSCSI traffic through
Microsoft iSCSI initiator or iSCSI offload. MPIO should be used instead of
QLogic network teaming for these ports.
17.

Troubleshooting Guidelines
Before you call support, make sure you have completed the following steps for
troubleshooting network connectivity problems when the server is using adapter
teaming.
1.
Make sure the link light is ON for every adapter and all the cables are
attached.
2.
Check that the matching base and intermediate drivers belong to the same
release and are loaded correctly.
3.
Check for a valid IP Address using the Windows ipconfig command.
4.
Check that STP is disabled or Edge Port/Port Fast is enabled on the switch
ports connected to the team or that LiveLink is being used.
5.
Check that the adapters and the switch are configured identically for link
speed and duplex.
